14 Best Vegan and Vegetarian Protein Sources

Quinoa

Most grains contain a small amount of protein, but quinoatechnically a seedis unique in that it contains more than 8 grams per cup, including all nine essential amino acids that the body needs for growth and repair, but cannot produce on its own. (Because of that, it's often referred to as a "perfect protein.") Plus, it's amazingly versatile: Quinoa can be added to soup or vegetarian chili during winter months, served with brown sugar and fruit as a hot breakfast cereal, or tossed with vegetables and a vinaigrette to make a refreshing summer salad.
